[Ink outlet assembly]

Fig. 3 is an exploded schematic diagram of some parts of the container related to the first embodiment of the present invention; Fig. 4 is the center of the ink outlet along a plane parallel to the front-back direction after the ink outlet assembly in the container related to the first embodiment of the invention is hidden. Stereoscopic view after line sectioning.

As shown in Figure 3, a part of the upper surface 13 is located on the bottom shell 1a, and another part of the upper surface 13 is located on the cover 1b. It can be realized that all of the upper surface 13 can be arranged on the bottom shell 1a, or it can be the upper surface All of 13 are provided on the face cover 1b. The ink chamber 10 is formed on the bottom shell 1a. The ink chamber 10 has a top surface 131 above and a second sub-bottom surface 142 below. Along the up-down direction, the top surface 131 is positioned below the top surface 13, and the second sub-bottom surface 142 is located above the lower surface 14, the first sub-lower surface 141 and the second sub-lower surface 142 are formed as part of the bottom surface of the ink chamber 10, the sub-front surface 111 is located on the first sub-lower surface 141 and the second sub-lower surface Between 142.

The ink outlet assembly 2 extends along the front-to-back direction and passes through the sub-front surface 111. As shown in FIG. The center line C parallel to the front-back direction, the front end of the ink outlet chamber 21 forms an ink outlet 22 for supplying ink to the outside, and the piston 23 keeps the ink outlet 22 sealed under the elastic force of the elastic member 24 . The piston 23 is rod-shaped, including a rod body 233 and a sealing end 231 located at one end of the rod body 233. Before the ink cartridge 100 is installed, under the elastic force of the elastic member 24, the sealing end 231 is forced to seal the ink outlet 22. Location.

The ink cartridge 100 also includes an air guide chamber 5 for introducing atmosphere into the ink chamber 10 . Before the ink cartridge 100 is installed, the air guide chamber 5 is sealed by an air guide film 18 (as shown in FIG. 7 ) so as not to communicate with the atmosphere. Before the existing ink cartridge 100 is installed, the user needs to tear off the air guide film 18 first, so that the air guide chamber 5 communicates with the inside and outside of the ink cartridge, and then install the ink cartridge 100 to the device. The ink is sucked out, the air pressure in the ink chamber 10 is reduced, and the external air is replenished into the ink chamber 10 through the conductor chamber 5, so that the pressure in the ink chamber 10 remains stable.

However, the situation that the user forgets to tear off the air guide film 18 always exists, especially for the user who uses this kind of equipment for the first time, the situation of forgetting to tear off the air guide film 18 is more likely to occur. When the ink cartridge 100 without tearing off the air guide film 18 is installed in the device, there will be a problem that the device cannot suck the ink out, thereby reducing the user experience. For this reason, the ink cartridge 100 involved in the present invention is set as: There is no need to tear off the air guide film 18 before being installed, the user only needs to install the ink cartridge 100 toward the device, and the air guide film 18 is opened during the installation process.

As shown in Figures 3 and 4, the ink outlet chamber 21 is communicated with the ink chamber 10 through the first communication hole 25, thus, the ink in the ink chamber 10 can be supplemented to the ink outlet chamber 21 without interruption; The cavity 21 is arranged adjacently, and the air guiding cavity 5 communicates with the ink cavity 10 through the air guiding channel, and the piston 23 extends from the ink outlet cavity 21 to the air guiding cavity 5. When the ink outlet 22 is opened, the piston 23 will guide the air The membrane 18 is pierced. Specifically, the air guide chamber 5 communicates with the ink outlet chamber 21 through the second communication hole 26, and the other end of the rod body 233 is set in a tapered shape to form a piercing portion 232, and the piercing portion 232 is located in the air guide chamber. 5, as the ink suction needle (not shown) enters the ink outlet cavity 21 through the ink outlet 22, the piston 23 is pushed backward by the ink suction needle, the sealing end 231 reaches the open position from the sealing position, and the ink outlet 22 is opened. , the elastic member 24 is elastically deformed, and the piercing portion 232 punctures the air guide film 18, and the air guide chamber 5 communicates with the atmosphere through the air guide hole 51; when the ink cartridge 100 is taken out from the device, the elastic member 24 pushes the piston 23 to move forward , the sealing end 231 returns to the sealing position from the open position, it can be seen that, in the process of the piston 23 moving forward and backward, the movement track of the piston 23 is limited by the second communication hole 26, thus, the second communication hole 26 can It is regarded as the motion trajectory control member of the piston 23.

As a second implementation, the air guide chamber 5 and the ink outlet chamber 21 can also be arranged at intervals, and communication holes are respectively arranged on the opposite surfaces of the two, and the piston 23 passes through the communication holes respectively so that the piercing part 232 reaches the guide hole. The air chamber 5, as the piston 23 is pushed backward by the ink-absorbing needle, the piercing part 232 will pierce the air-guiding membrane 18, this structure is beneficial to prevent a small amount of ink leaking from the ink outlet chamber 21 from entering the air-guiding chamber 5, When the user takes out the ink cartridge, the ink leaks from the air guide cavity 5 and pollutes the user's hand.

As a third implementation, the piercing portion 232 is formed separately from the piston 23 as an independent component. Trigger, through this intermediate component, the piston 23 does not have to extend to the air guide chamber 5, thereby reducing the sealing requirements between the ink outlet chamber 21 and the air guide chamber 5, for example, magnetic parts are installed on the piston 23 and the piercing part 232, and the magnetic force The piercing part 232 can move along with the movement of the piston 23; further, by adjusting the magnitude and direction of the magnetic force, the magnitude and direction of the force transmitted from the piston 23 to the piercing part 232 can also be controlled, so that the piercing part 232 can more accurately puncture the air-conducting membrane 18; further, the intermediate part can also be set to: after the piercing part 232 pierces the air-conducting film 18, the intermediate part will puncture the part 232 from the guide The air hole 51 is removed to prevent the piercing portion 232 from blocking the air hole 51 and affecting the communication efficiency between the air chamber 5 and the atmosphere.

Through the above description, the piston 23/sealing end 231 can be considered as the triggering part, and the piercing part 232 can be considered as the triggered part. When the triggering part 23 is pushed by the ink-absorbing needle, the sealing end 231 moves from the sealing position to the In the open position, the triggered part 232 is linked with the triggering part 23/231, and the triggering part 23 triggers the triggered part 232 to puncture the air-guiding film 18, so that the air-guiding chamber 5 communicates with the ink chamber 10 and the atmosphere.

[lock components]

As mentioned above, when the ink cartridge 100 is installed in the ink cartridge accommodating chamber 200, the ink suction needle abuts against the piston 23 so that the elastic member 24 is elastically deformed, and then the ink cartridge 100 has a tendency to move backwards, in order to prevent the ink cartridge 100 from being Pushing out, the locking assembly 4 will be combined with the limit rod 203 in the ink cartridge accommodation cavity 200, so that the ink cartridge 100 is kept at a predetermined installation position.

As shown in Figure 4, Figure 7 and Figure 8B, the locking assembly 4 includes a base 41 connected to the housing 1 and a locking member 42 arranged on the base 41, at least one of the base 41 and the locking member 42 is set to Can move up and down; when the ink cartridge 100 is installed toward the ink cartridge accommodating cavity 200, along the up and down direction, the locking assembly 4 is higher than the limit rod 203, thus, during the installation process of the ink cartridge 100, the locking assembly 4 will be in contact with the limit rod 203 Interference occurs, and at least one of the base 41 and the locking member 42 is forced to move downward until the limit rod 203 crosses the highest point of the locking assembly 4, and then at least one of the base 41 and the lock member 42 moves upward to the limit of the limit rod 203 In the front, finally, the ink cartridge 100 is prevented from retreating backward through the abutment of the locking member 42 and the limit rod 203 .

Preferably in the present invention, the base 41 is integrally formed with the bottom shell 1a, the base 41 extends upward from the upper surface 13, the locking member 42 is set to be elastic and can move in the up and down direction, the locking member 42 is installed above the base 41 Elastic rubber, the elastic rubber is installed in an arc shape, thus, when the limiting rod 203 is in contact with the elastic rubber, the inclined surface in front of the elastic rubber can guide the limiting rod 203, and as the limiting rod 203 crosses At the apex of the elastic rubber, when the ink cartridge 100 is installed to a predetermined position, the inclined surface behind the elastic rubber abuts against the limit rod 203 .

As a simpler implementation, the locking assembly 4 can also be set to have no elasticity. At this time, the locking assembly 4 forms a hard contact with the stop bar 203; Below the ink cartridge 100, the ink suction needle exerts a backward thrust on the ink cartridge 100. Above the ink cartridge 100, the extrusion of the limit rod 203 and the locking assembly 4 makes the ink cartridge 100 receive a forward thrust. As shown in FIG. 8B, the ink cartridge 100 as a whole will have a tendency to rotate downward and forward around the contact point between the ink suction needle and the piston 23, and the ink cartridge 100 may shake during the working process of the device.

However, when at least one of the base 41 and the locking member 42 in the locking assembly 4 is configured to move in the up and down direction, not only can the resistance of the ink cartridge 100 be reduced during installation, but also when the ink cartridge 100 is installed to a predetermined position, The limiting rod 203 presses the locking member 42 so that the ink cartridge 100 is subjected to a downward pressing force, and the tendency of the ink cartridge 100 to rotate downward and forward can be stopped.

Further, as shown in FIG. 3 , FIG. 4 and FIG. 7 , the ink cartridge 100 also includes a hook portion 133 arranged at the rear of the housing 1 , along the front-to-back direction, a concave portion 132 is formed between the hook portion 133 and the locking assembly 4 to lock The assembly 4, the concave portion 132 and the hook portion 133 are arranged in sequence from front to back. When the ink cartridge 100 needs to be taken out, the concave portion 132 forms an accommodating portion for the user’s fingers, and by applying a backward pulling force to the hook portion 133, the limit rod 203 once again crosses the highest point of the locking assembly 4, and the ink cartridge 100 is elastically Part 24 retreats backward under the action of the elastic restoring force.

Preferably, when the chip holder 31 is at the first position, the plane where the chip electrical contact portion 322 is located is also inclined relative to the front-to-back direction, as shown in FIG. Above, in this way, along the up and down direction, the moving distance of the chip holder 31 can be reduced, the electrical contact part 322 can abut against the contact pin faster, and the structure of the chip holder 31 can also be simplified; 315a is inclined forward, so that the force receiving surface 315a is more likely to be in contact with the blocking wall 202b, and the force receiving surface 315a will not lose contact with the blocking wall 202b when the chip holder 31 rotates in the direction indicated by r.

How the chip holder 31 is kept in a state inclined relative to the front-rear direction will be described below with reference to FIG. 3 , FIG. 7 and FIG. 8B .

As shown in the part R2 in Fig. 7, the distance from the front end of the chip holder 31 to the rotation axis L is far greater than the distance from the rear end of the chip holder 31 to the rotation axis L, and in the natural state, the chip holder 31 has the ability to rotate along the r' direction trend; when the chip 32 is mounted on the chip holder 31, most of the weight of the chip 32 is located in front of the rotation axis L, therefore, the chip assembly 3 as a whole has a tendency to rotate along the r' direction.

In order to keep the chip holder 31 at the first position in the aforementioned inclined state, the housing 1 is further provided with a holding portion, and the chip holder 31 is provided with a held portion. As shown in FIG. 3 , the holding portion includes a first holding portion 134 for holding the chip holder 31 at the first position and a second holding portion 135 for holding the chip holder 31 at the second position, and the held portion includes a The first held portion 311a contacting the first holding portion 134 and the second held portion 311b for contacting the second holding portion 135, the first held portion 311a and the second held portion 311b are adjacently arranged, and the first held portion 311a is adjacent to the second held portion 311b. The holding part 134 and the second holding part 135 are also arranged adjacently. When the chip holder 31 is installed, the first holding part 134 and the second holding part 135 enter the gap between the first held part 311a and the second held part 311b. In the region, the first holding portion 134 abuts against the first held portion 311a, so that the chip holder 31 is held at the first position inclined upward relative to the front-rear direction, as shown by the part R3 in FIG. 8B , when the force-bearing surface 315a When the chip holder 31 is blocked by the blocking wall 202b and rotates in the direction indicated by r around the rotation axis L, the first holding part 134 is out of contact with the first held part 311a until the chip holder 31 reaches the second position. At this time, The second holding portion 135 abuts against the second held portion 311b, and the chip holder 31 is held at the second position.

It can be seen from this that, when the chip holder 31 is in the first position, the upward tilt angle relative to the front-rear direction can be determined by the contact position between the first holding part 134 and the first held part 311a. Similarly, the chip holder 31 is in the second position. The angle of upward inclination relative to the front-rear direction can be determined by the abutment position between the second holding part 134 and the second held part 311b, between the first holding part 134 and the first held part 311a and the 135 and the second held portion 311b can form at least one of surface contact, line contact and point contact; in the present invention, surface and surface contact are formed between the first holding portion 134 and the first held portion 311a, The second holding portion 135 forms surface and line contact with the second held portion 311b, the first holding portion 134 is a slope inclined backward relative to the front-rear direction, and the second holding portion 135 is a plane parallel to the front-rear direction.

Further, the holding portion further includes a third holding portion 136 adjacent to the second holding portion 135. When the chip holder 31 is at the first position, except that the first holding portion 134 is in contact with the first held portion 311a, the third holding portion 136 The holding portion 136 is also kept in contact with the main body 311 , and the chip holder 31 can be positioned at the first position more stably.

Furthermore, the chip assembly 3 can also be provided with a reset member combined with the chip holder 31, such as a tension spring or a compression spring, so that the chip holder 31 is kept in an upwardly inclined posture relative to the front-to-back direction at the first position. When the first position moves to the second position, the reset member elastically deforms, and when the force-bearing surface 315a is out of contact with the blocking wall 202b, the chip holder 31 will move from the second position to the first position under the elastic reset force of the reset member sports.

The chip holder 31 can also move between the first position and the second position in a translational manner. For example, a force conversion mechanism is provided between the force receiving part 315 and the support part. When the force receiving surface 315a and the supporting part When the blocking wall 202b is in contact, the force conversion mechanism can convert the force received by the force receiving surface 315a to be applied to the supporting part in the up and down direction, thereby forcing the chip holder 31 to move from the first position to the second position, located in the chip holder 31 The electrical contact portion 322 of the contact pin 204 is in contact with the contact pin 204. When the force-bearing surface 315a is out of contact with the blocking wall 202b, the chip holder 31 returns to the first position from the second position under the action of its own gravity; in this embodiment, The chip holder 31 can be arranged obliquely or horizontally.

The mode in which the force-bearing surface 315a is in contact with the blocking wall 202b to make the chip holder 31 move has been described above, however, according to the technical ideas of the present invention, the force-bearing surface 315a can also be arranged at other positions of the chip holder for contact with the ink cartridge accommodating chamber. 200, for example, the force-bearing surface 315a is located on the left and right sides of the main body 31. During the installation process of the ink cartridge 100, the force-bearing surface 315a is in contact with the left and right sides of the ink cartridge accommodating chamber 200, thereby forcing the chip holder 31 to moving between the first position and the second position.

In this embodiment, the chip 32 is installed in a rotatable manner. As shown in FIGS. 9 and 10 , the chip assembly 3 includes a movable part 33 and a chip 32. 32 and the movable part 33 can be rotatably installed on the housing 1, as shown in Figure 11, the movable part 33 includes a movable plate 331, and a force plate 333 and a forcing plate 332 combined with the movable plate 331, preferably , the force plate 333 has an inclined contact surface 3331, the contact surface 3331 is inclined from front to bottom to rear and upper, and the forcing plate 332 has an inclined forcing surface 3321, and the forcing surface 3321 is inclined from the rear to the front and upward. The movable part 33 can be rotated or translated. When the movable part 33 is rotated, the movable part 33 also includes a rotating part 334 combined with the movable plate 331 .

Fig. 12A is a schematic diagram of the relative position of the chip component and the container accommodating cavity before the container according to the second embodiment of the present invention is installed; Fig. 12B is a relative position of the chip component and the container accommodating cavity after the container according to the second embodiment of the present invention is installed schematic diagram.

As shown in FIG. 12A , the chip 32 also includes a mating portion 325 disposed on the substrate 321, and the mating portion 325 is mated with a mated portion (not shown) disposed on the housing 1. In some embodiments, the mating portion 325 It is set as a protrusion, and the matched part is set as a groove. On the contrary, the matching part 325 can also be a groove set on the substrate 321. Correspondingly, the matched part 101 is a protrusion set on the housing 1, and the protrusion 325 is rotatably installed in the groove 101 . Through the combination of the mating portion 325 and the mated portion 101, the chip 32 is combined with the housing 1 in a rotatable manner. Preferably, the mating portion 325 is arranged closer to the rear end of the substrate 321, so that most of the weight of the chip 32 It will be located in front of the matching portion 325 so that the chip 32 has a tendency to rotate around the direction opposite to the direction shown by r2 in FIG. 12A .

Before the ink cartridge 100 is installed, the chip 32 is located at the first position, and the chip 32 abuts against the movable part 33 and is kept in an upwardly inclined posture relative to the front-rear direction in FIG. 12A . At the lowest point of the stylus chamber 202 , in this way, the chip assembly 3 will not interfere with the stylus chamber 202 when the ink cartridge 100 is installed toward the ink cartridge accommodating chamber 200 . When the contact surface 3331 of the movable member 33 abuts against the abutting portion 205 in the ink cartridge accommodating chamber 200, as the ink cartridge 100 continues to be pushed forward, the abutting portion 205 exerts a force on the contact surface 3331, forcing the movable member 33 Rotate around the rotating part 334 in the direction indicated by r1, and the pushing part 332 forces the chip substrate 321, so that the substrate 321 rotates around the protrusion 325 in the direction indicated by r2, and the electrical contact part 322 gradually moves away from the top surface 131/ink outlet 22 until Chip 32 reaches the second position shown in FIG. 12B.

As shown in FIG. 12B , the force receiving portion 333 is in contact with the contact portion 205 , the forcing surface 3321 is in contact with the substrate 321 , and the electrical contact portion 322 is in contact with the front surface of the contact pin 204 . When the ink cartridge 100 is taken out backward, the force-receiving part 333 is no longer in contact with the contact part 205, and under the action of the gravity of the movable part 33 itself and the gravity of the chip 32, the movable part 33 rotates around the rotating part 334 along the direction indicated by r1. Rotate in the opposite direction, at the same time, the chip 32 also rotates around the protrusion 325 in the opposite direction to the direction indicated by r2, the electrical contact portion 322 is out of contact with the contact pin 204, and the chip 32 returns from the second position to the first position.

Preferably, a reset member can also be provided between the movable part 33 and the housing 1 or between the chip 32 and the housing 1. When the chip 32 is in the second position, the reset member accumulates potential energy. When the connecting portion 205 abuts, the reset member releases the potential energy, and the movable member 33 and the chip 32 can quickly return from the second position to the first position; It is arranged on the housing 1, and the groove combined with the protrusion 325 is arranged on the substrate 321. Therefore, for the chip 32, the position where the protrusion 325 or the groove is located is the positioning part of the chip 32, and the chip 32 can rotate around the positioning part. turn. It has been described above that the movable part 33 moves in a rotational manner. It can be realized that the movable part 33 can also be set to move in translation along the front and rear directions. When the ink cartridge 100 is installed, the force receiving part 333 is abutted by the abutting part 205 , the movable part 33 moves backward and pushes up the chip substrate 321, so that the chip 32 reaches the second position where the electrical contact part 321 is in contact with the contact pin 204. The part 33 translates from back to front under the action of the elastic force of the elastic part or the magnetic force of the magnetic part, and the chip 32 returns from the second position to the first position.

Embodiment Three

This embodiment is a further improvement on Embodiment 2. As shown in FIG. 13 , the force receiving portion 333 is abutted against the bottom surface 206 of the ink cartridge containing cavity 200 , and after the ink cartridge 200 is installed, the force receiving portion 333 is all located below the bottom surface 206 , the state of the movable part 33 is more stable. Further, in this embodiment, the ink cartridge 100 also includes a reset member 19 located between the chip 32 and the housing 1. Preferably, the reset member 19 is such as a compression spring/tension spring, Elastic components such as rubber blocks, more preferably in this embodiment, the reset member 19 is a rubber block.

As shown in Figure 13, the rubber block 19 includes an upper part 19a and a lower part 19b that are combined with each other, and the rubber block 19 can be stably placed on the top surface 131 of the ink chamber through the planar bottom surface 193 below the lower part 19b, along the front-rear direction , the maximum size of the upper part 19a is smaller than the maximum size of the lower part 19b. It is more preferable that the size of the bottom surface 193 in the front-to-back direction is the largest, which is conducive to the rubber block 19 being kept stably on the top surface 131, or when the rubber block 19 touches the top surface. Face 131 can remain stable.

Further, the outer surface of the upper part 19a is arc-shaped to facilitate receiving force, the first elongated hole/first oval hole 191 extending along the up-down direction is arranged on the upper part 19a, and the second elongated hole extending along the front-rear direction /The second oval hole 192 is arranged on the lower part 19b, and the rubber block 19 is combined with the chip 32 through the first elongated hole/the first oval hole 191, specifically, the protrusion 325 passes through the first elongated hole/the first oval hole 191 .

Before the ink cartridge 100 is installed, the relative position of the chip 32 and the rubber block 19 is not limited, the two can be in contact with each other, and can also be kept separated from each other. First position; when the ink cartridge 100 is installed, the bottom surface 206 of the ink cartridge accommodating chamber presses the stressed portion 333, and the forcing portion 332 pushes the substrate 321, so that the end of the chip 32 provided with the electrical contact portion 322 moves upward until the electrical contact portion 322 Contacting the contact pin 204 , correspondingly, the rear side of the protrusion 325 moves downward, and the rubber block 19 is compressed. At this time, the chip 32 is in the second position where the communication connection is established between the electrical contact portion 322 and the contact pin 204 . When the ink cartridge 100 is taken out, the force receiving portion 333 is no longer pressed by the bottom surface 206 of the ink cartridge accommodating chamber, and the chip 32 returns from the second position to the first position under the action of its own gravity or/and the reset force of the rubber block 19 .

As mentioned above, the first elongated hole/first elliptical hole 191 extends in the up-down direction, thus, the upper portion 19a can have a larger deformation along the up-down direction, and the second elongated hole/second elliptical hole 192 extends in the front-back direction. Extending, along the up and down direction, the deformation of the lower part 19b is smaller than that of the upper part 19a, but the lower part 19b can ensure that the rubber block 19 is in stable contact with the top surface 131 of the ink chamber, thereby ensuring that the rubber block 19 is pressed by the chip 32 no displacement occurs.

Simplified, the second elongated hole/second oval hole 192 can also be canceled. At this time, the rubber block 19 only retains the first elongated hole/first oval hole 191. Similarly, along the up-down direction, the upper part 19a The amount of deformation is greater than that of the lower part 19b; or, the first elongated hole/first elliptical hole 191 is canceled, and the rubber block 19 only retains the second elongated hole/second elliptical hole 192. At this time, along the up-down direction, the upper part The amount of deformation of 19a is smaller than that of the lower portion 19b. No matter how the shape of the upper part 19a and the lower part 19b of the rubber block 19 changes, or how the shape of the elongated hole/elliptical hole changes, the bottom surface 193 of the lower part 19b is preferably a plane.

Those skilled in the art can understand that, if the bottom surface 193 is not set as a plane, it can also be set as a friction surface with a relatively large frictional force, or the lower part 19b can be set as a structure similar to a suction cup, with a rubber block 19 is preferably able to maintain no displacement relative to the top surface 131 of the ink chamber when subjected to the force of the chip 32 .

Embodiment four

Different from Embodiment 2 and Embodiment 3, when the chip 32 in this embodiment is in the first position, the movable part 33 is not in contact with the chip 32, and when the chip 32 is in the second position, the movable part 33 is in contact with the chip 32, That is to say, the chip 32 in this embodiment is balanced on the front and rear sides of the protrusion 325 through its own structural arrangement. The "balance" here means that the chip 32 only relies on its own The protrusion 325 of the chip 32 realizes a static state at the first position. At this time, except the protrusion 325 is in contact with the housing 1 , other parts of the chip 32 are not in contact with the housing 1 .

For example, if it is necessary to make the chip 32 remain substantially parallel to the front-to-back direction in the first position, the chip 32 can be arranged so that along the front-to-back direction, the mass between the front end of the chip 32 to the protrusion 325 is the same as the mass between the rear end of the chip 32 to the protrusion 325. If it is necessary to keep the chip 32 in the first position inclined to the front-rear direction, and the front end provided with the electrical contact 322 is inclined upward, then the chip 32 can be set so that, along the front-rear direction, the chip 32 The moment between the front end of the chip 32 and the protrusion 325 is smaller than the moment between the rear end of the chip 32 and the protrusion 325 .

In this embodiment, the chip 32 also includes a counterweight 326 for adjusting the mass on both sides of the protrusion 325. According to the posture requirements of the chip at the first position, the counterweight 326 can be installed on the substrate 321 or the battery 324, as shown in the figure As shown in 14, the chip 32 is located at the first position, and the front end where the electrical contact portion 322 is located is inclined upwards, and the counterweight 326 is installed behind the protrusion 325, as shown by the part R4 in FIG. 14 , the substrate 321 and the movable part A gap g is formed between the pushing parts 332 , and the chip 32 is held by the protrusion 325 in a posture in which the front end is inclined upward.

When the ink cartridge 100 is installed, the force-receiving portion 333 is abutted by the abutment portion 205, the forcing portion 332 starts to contact the substrate 321, and the chip 32/substrate 321 rotates from the first position to the second position until the electrical contact portion 322 is in contact with the substrate 321. When the contact pin 204 is in contact, when the ink cartridge 100 is taken out backwards, the force-receiving part 333 is no longer abutted by the abutment part 205, the movable part 33 is gradually reset, and the chip 32 is also gradually returned from the second position to the first position under the action of its own gravity. a location.

Compared with the chip component 3 in the above-mentioned embodiment, the chip component 3 in this embodiment is simplified to only include the chip 32, not only the structure of the chip component 3 is simplified, correspondingly, the structure of the ink cartridge 100 is also simplified; on the other hand , in the first position, the chip 32 is not in contact with the movable part 33, and before the force-receiving part 333 abuts against the abutment part 205, even if the movable part 33 slightly interferes with the components in the ink cartridge accommodating cavity 200, the movable part 33 will Moving, the chip 32 will not move to a position where it interferes with the contact pin seat 202 , therefore, the requirement for dimensional accuracy of the movable part 33 can be reduced.

Further, the chip 32 in this embodiment can also be set so that, in the first position, the chip 32 still achieves the above-mentioned balance through its own structural setting, but the pushing part 332 is infinitely close to the substrate 321, visually, the two However, when the pushing part 332 is moved away from the substrate 321, the chip 32 remains still; this structural arrangement can reduce the moving distance of the pushing part 332.

Embodiment five

Fig. 15 is an exploded view of some parts of the container according to the fifth embodiment of the present invention; Fig. 16 is a view of the container and the container accommodating chamber in the device viewed from the left and right direction before the container according to the fifth embodiment of the present invention is installed in the container accommodating chamber side view.

Along the front-to-back direction, the chip 32 is divided into a first portion 321a located in front of the protrusion 325 and a second portion 321b located behind the protrusion 325 with the position of the protrusion 325 as the boundary. The electrical contact portion 322 is located in the second portion 321b. After the chip 32 is mounted, the second part 321b is located at a higher position than the first part 321a along the up-down direction, or in other words, the second part 321b is located above the first part 321a, and in the second part 321b, at least the electrical contacts The part 322 protrudes to the outside of the housing 1. Preferably, the first part 321a does not exceed the housing 1. When the chip 32 is installed toward the inkjet printer along with the ink cartridge 100, the first part 321a positioned at the front will not come into contact with the inkjet printer. The inner walls interfere, thereby speeding up the installation speed of the ink cartridge 100; as shown in Figure 16, the ink cartridge 100 also includes a light attenuation part 102 arranged adjacent to the chip 32 along the front and rear direction, during the installation process of the ink cartridge 100, the light attenuation The part 102 can be detected by the inkjet printer. When the light attenuating part 102 is located in front of the chip 32, along the vertical direction, at least the electrical contact part 322 is located above the light attenuating part 102, and the lowest point of the contact pin 204 is in contact with the electrical contact part. 322 intersects on a plane D perpendicular to the up-down direction (as shown by the dotted line in Figure 16); along the front-to-back direction, the electrical contact portion 322 is farther away from the ink outlet than the light attenuation portion 102, even if there is ink leaking from the ink outlet, the electrical contacts The contact portion 322 is also less affected.

As shown in FIG. 16, when the ink cartridge 100 is installed in the forward direction, before the electrical contact portion 322 contacts the contact pin 204, the electrical contact portion 322 will interfere with the contact pin seat blocking wall 202b, and as the ink cartridge 100 continues Installation, the electrical contact portion 322 is pressed down by the blocking wall 202b together with the second portion 321b so that the chip 32 rotates clockwise around the protrusion 325 (as viewed from left to right in FIG. 15 in the r2 direction), until the electrical contact portion 322 Going over the barrier wall 202b and entering the contact pin chamber 202a, finally, the chip 32 returns to the position where the second part 321b is above the first part 321a under the action of the holding assembly described below, and the electrical contact part 322 keeps in contact with the contact pin 204 .

When the ink cartridge 100 is taken out in the backward direction, the second part 321b located in the stylus cavity 202a may interfere with the side of the barrier wall 202b facing the stylus cavity, at this time, the second part 321b can be entered by reducing the The size of the stylus chamber 202a is such that the second part 321b is less interfered, and the operator can pull the ink cartridge 100 backward to take out the ink cartridge without using external parts.

The holding components used to hold the chip 32 at the second portion 321b higher than the first portion 321a can be external components other than the chip 32/substrate 321 or components constituting the chip 32/substrate 321 itself, which will be described below.

When the holding component is from an external component other than the chip 32/substrate 321, as shown in FIG. The moment from the front end of the first part 321a to the protrusion 325 is greater than the moment from the rear end of the second part 321b to the protrusion 325, so that when the chip 32 is installed, the second part 321b will appear higher than the first part 321a under the action of gravity. status. When the chip 32 passes over the blocking wall 202b, the blocking wall 202b presses the second part 321b, so that the whole chip 32 rotates around the protrusion 325 in the direction shown by r2 until the second part 321b reaches the contact pin chamber 202a, and then the holding assembly Under the action of the chip 32, the chip 32 returns to the state where the second part 321b is higher than the first part 321a; preferably, the moment of the counterweight 326 to the protrusion 325 is set to be much larger than the moment of the electrical contact 322 to the protrusion 325, thus, The electrical contact portion 322 can maintain close contact with the contact pin 204 .

Realizable, the holding component can also be a magnet set arranged on the chip 32 /substrate 321 and the housing 1 , and use magnetic force to keep the chip 32 in a state where the second part 321b is higher than the first part 321a.

When the holding component is a part from the chip 32 itself, the holding component is at least a part of the first part 321a. At this time, the material of at least a part of the first part 321a is different from other parts of the substrate 321. The material of at least a part of the first part 321a The density is higher than the density of the material (such as resin, glass fiber, aluminum substrate, etc.) that usually forms the substrate. Optionally, metal, solid wood, high-density rubber, etc. are applicable.

Further, in the process of taking out the ink cartridge 100, in order to enable the chip 32 (second part 321b/electrical contact portion 322) to move relative to the housing 1, specifically, the part of the chip 32 entering the contact pin cavity 202a can be removed from the contact pin The interior of the cavity 202a easily crosses the barrier wall 202b to reach the outside of the stylus cavity 202a. The chip assembly 32 also includes auxiliary parts. Similarly, the auxiliary parts can be parts from the outside of the chip 32 or parts from the chip 32 itself. The following are respectively Be explained.

When the auxiliary part is an external component other than the chip 32, as shown in FIG. 15, the auxiliary part is an elastic body 35 located between the substrate 321 and the housing 1. The chip 32 can be kept in a state where the second part 321b is higher than the first part 321a by the above-mentioned retaining assembly without the action of the elastic body 35. When the chip 32 moves backward with the ink cartridge as a whole, the second part 321b faces the blocking wall 202b. When one side of the stylus cavity interferes, the chip 32 is overturned or pressed downward to avoid the blocking wall 202b. Finally, the second part 321b of the chip 32 crosses the blocking wall 202b, and the ink cartridge 100 is taken out smoothly. After the ink cartridge accommodating cavity is taken out, the auxiliary part 35 forces the chip 32 to return to the first position from the second position, therefore, the auxiliary part 35 can also be regarded as a kind of holding component.

Optionally, the elastic body 35 can also be fixedly mounted on the casing 1 , and similarly, the elastic body 35 will only function when the chip 32 interferes with the blocking wall 202 b during the removal of the ink cartridge 100 .

When the auxiliary part is a self-component of the chip 32, the auxiliary part can be an active connection mechanism arranged on the substrate 321, for example, the first part 321a of the substrate 321 is movably connected to the second part 321b, when the second part 321b When interfering with the blocking wall 202b, the second part 321b moves relative to the first part 321a/housing 1 and avoids the blocking wall 202b.

In some embodiments, the auxiliary part is at least a part of the substrate 321, and at least a part of the substrate is made of a flexible circuit board.

As shown in Figure 20, when the force receiving part 315 abuts against the blocking wall 202b, the main body 311 rotates around the recessed part 319 as a whole, the connecting part 318 deforms, and the side where the electrical contact part 322 is located swings upward until the electrical contact part 322 and the contactor The needle 204 contacts, and the chip 32 reaches the second position from the first position; when the force-receiving part 315 is out of contact with the blocking wall 202b, the connecting part 318 resets, causing the main body 311 to rotate reversely around the recessed part 319, and the chip 32 moves from the second position to the second position. The position returns to the first position.

The above embodiment describes that after the chip 32 reaches the second position from the first position, the electrical contact portion 322 is in contact with the front surface of the contact pin 204, however, the structure of the electrical contact portion 322 or the structure of the chip 32 can also make the chip When 32 reaches the second position, the electrical contact portion 322 is in contact with the rear surface of the contact pin 204 or the electrical contact portion 322 is in contact with the front surface and the rear surface of the contact pin 204 at the same time, for example, the electrical contact portion 322 is arranged as in Embodiment 5 The above protrudes from the housing 1 backward and upward. At this time, the electrical contact portion 322 can contact the rear surface of the contact pin 204; or the electrical contact portion 322 is set in a U shape. The front surface and the rear surface of the needle 204 are in contact at the same time. Compared with the electrical contact portion in the prior art that contacts the lower tip of the contact pin 204, the contact area between the electrical contact portion 322 and the contact pin 204 in the present invention is larger and more efficient. It is beneficial to maintain a stable electrical connection between the electrical contact portion 322 and the contact pin 204 .

Based on the inventive concept of the present invention, the chip holder main body 311 in the first embodiment and the seventh embodiment can also be regarded as the movable part in the respective embodiments, which has the same function as the movable part in the second embodiment to the sixth embodiment. The chip holder main body 311 is configured to be movable relative to the housing 1, and the chip holder main body 311 is used to receive force from the ink cartridge accommodating cavity 200, thereby making the electrical contact portion 322 reach the second position from the first position, when the When the force is removed, the electrical contact portion 322 returns from the second position to the first position.

The beneficial effects of the present invention are as follows:

The lower surface 14 is a plane, and the ink cartridge 100 can be installed and removed in a direction parallel to the front-back direction. During the installation and removal process, the movement track of the ink cartridge 100 is simpler, and accordingly, the structures of the equipment and the ink cartridge 100 can be simplified .

The piercing part 232 that can be linked with the piston 23 is set in the air guide chamber 5. During the installation process of the ink cartridge 100, when the ink suction needle pushes the piston 23 to move backward, the piercing part 232 will be used to seal the air guide hole 51. The air guide film 18 is pierced, so that the ink chamber 10 communicates with the atmosphere, which saves the user from the operation of tearing off the air guide film 18 before installing the ink cartridge.

Preferably, one end of the piston 23 is formed as a sealing end 231 that seals the ink outlet, and the other end is formed as a piercing portion 232 that can pierce the air-conducting film 18, that is, the piston 23 and the piercing portion 232 are integrally formed, and the piston 23 is formed in the direction of the piercing portion 232. At the same time as the rearward movement, the air guide membrane 18 is directly pierced by the piston 23, and the thrust applied to the piston 23 by the ink suction needle can be effectively transmitted to the piercing part 232, and at the same time, the structure of the ink cartridge will become simpler.

In some embodiments, when the ink outlet chamber 21 on which the piston 23 is installed and the air guide chamber 5 are spaced apart from each other, through holes sealed by seals are respectively provided on the opposite surfaces of the two. Before the ink cartridge 100 is installed, the outlet The ink chamber 21 and the air guide chamber 5 are isolated from each other, and the piston 23 is all located in the ink outlet chamber 21. When the ink cartridge 100 is installed, the ink suction needle pushes the piston 23 to move backward, and the piercing part 232 passes through the seal to reach the air guide chamber 5 And the gas-guiding film 18 is punctured, and in the motion process of the piston 23, the sealing member contacts the outer surface of the piston rod body 233, and the sealing of the ink outlet chamber 21 and the air-guiding chamber 5 is guaranteed.

Further, the ink outlet chamber 21 is adjacent to the air guide chamber 5, and the two communicate through the second communication hole 26, the seal is installed on the second communication hole 26, the piston 23 passes through the second communication hole 26, Make the piercing part 232 be located in the air guide chamber 5, while the seal is in contact with the outer surface of the piston rod body 233, the ink outlet chamber 21 and the air guide chamber 5 still remain in a state of being isolated from each other; when the piston 23 moves backward, the pierced The portion 232 can puncture the air-conducting membrane 18 faster.

Furthermore, the piston 23 and the puncturing part 232 are formed separately, and the two are connected through an intermediate part. By adjusting the intermediate part, the strength and direction of the piercing part 232 piercing the air-conducting membrane 18 can be adjusted. At the same time, Also according to demand, delay the moment when the air guide film 18 is pierced, for example, the user just needs to install the ink cartridge 100 to the equipment, and does not need to perform imaging operation immediately after installation, the air guide film 18 does not need to be placed on the ink cartridge 100. If it is punctured during the installation process, at this time, the force of the ink-absorbing needle pushing the piston 23 to move backward can be stored by the intermediate part, and when the ink-absorbing needle starts to suck out ink from the ink outlet chamber 21, the flow of the ink will cause the intermediate part to release the action Force, so that the piercing part 232 pierces the air-conducting membrane 18, and at this time, the piercing part 232 can also be considered as being triggered by the piston 23. Based on the technical idea of the present invention, the movement of the piston 23 can be understood as, when the piston 23 deviates from the sealing position, the gas-guiding membrane 18 is pierced, and the timing of the gas-guiding membrane 18 being pierced can be set according to requirements.

As shown in Fig. 4, Fig. 7 and Fig. 8B, along the up-down direction, the air guiding cavity 5 is located in the cavity 17 between the second sub-lower surface 142 and the lower surface 14, and the air guiding cavity 5 does not exceed the lower surface 14, During the installation and removal of the ink cartridge 100, the air guide chamber 5 will not interfere with the device, and the air guide film 18 can be effectively protected. Along the front-rear direction, the air-guiding chamber 5 and the ink outlet chamber 21 are disposed near the front, and behind the air-guiding chamber 5 , the cavity 17 forms a space allowing the piercing part 232 to move.

The chip holder 31 is configured to be movable between the first position and the second position. In the chip 32, at least the electrical contact portion 322 is installed on the chip holder 31, and can move along with the chip holder 31 between the first position and the second position. Move between two positions, in the first position, the electrical contact portion 322 is not in contact with the contact pin 204 in the device, in the second position, the electrical contact portion 322 is in contact with the contact pin 204, and along the up and down direction, in the second position The distance between the electrical contact portion 322 and the centerline C/ink cartridge lower surface 14 of the ink chamber top surface 131/the ink chamber 21 is greater than the distance between the electrical contact portion 322 at the first position and the ink chamber top surface 131/the ink chamber 21 The distance between the center line C/the lower surface 14 of the ink cartridge, on the one hand, during the installation process of the ink cartridge 100, the chip seat 31/electrical contact portion 322 will not interfere with the device; on the other hand, when the device is working, along the up and down direction, The electrical contact part 322 is as far away from the ink outlet chamber 21 as possible, and the vibration generated when the ink sucking needle absorbs ink from the ink outlet chamber 21 is unlikely to affect the contact between the electrical contact part 322 and the contact pin.

In addition, at least the electrical contact portion 322 can move between the first position and the second position along with the die holder 31 , thus, the accuracy requirement of the mounting position of the electrical contact portion 322 on the die holder 31 can be reduced.

The electrical contact portion 322 is located in front of the chip holder 31. When the chip holder 31 is rotated, the rotation axis L of the chip holder 31 is closer to the rear end of the chip holder 31. Under the action of the chip holder 31's own gravity, the chip holder 31 It has a tendency to rotate around the axis of rotation L along the direction shown by r' in FIG. The direction shown returns from the second position to the first position; it can be seen that this arrangement enables the chip holder 31 to return from the second position to the first position without relying on external force, and the structure of the chip assembly 3 can be simplified.

The top surface 131 of the bottom case is lower than the upper surface 13 of the casing. As shown in FIG. The seat 31 can be protected by the shell 1, and only exposed through the top of the shell 1, the chip seat 31 and the electrical contact portion 322/chip 32 mounted on the chip seat can be effectively protected by the shell 1, reducing the electrical contact portion 322/ The probability that chip 32 is damaged.

When the chip holder 31 is in the first position, the chip holder 31 is inclined upward relative to the front-to-back direction, and correspondingly, the electrical contact portion 322 on the chip holder 31 is also inclined upward relative to the front-rear direction. In the translation mode, the electrical contact part 322 can be in contact with the contact pin 204 faster. Compared with the existing arrangement in which the electrical contact part 322 is parallel to the front and rear directions, the distance that the chip holder 31 moves in the up and down direction is a certain value. Obviously, when the chip holder 31 is in the second position, the electrical contact portion 322 in the present invention is in closer contact with the contact pin 204 .

The locking member 42 is made of elastic rubber, and a certain frictional force can be generated between the limit rod 203 and the elastic rubber 42. This frictional force is beneficial to overcome the backward thrust of the ink-absorbing piston 23 and prevent the ink cartridge 100 from being pushed out backwards. At the same time, utilize the elasticity of the elastic rubber 42 to reduce the resistance of the stop rod 203 to the ink cartridge 100 during the installation and removal of the ink cartridge 100; There is a downward force, which can prevent the ink cartridge 100 from rotating downward and forward with the contact point of the ink suction needle and the piston 23 as the center of circle.

Along the up and down direction, the locking assembly 4 and the chip assembly 3 are located above and away from the ink outlet assembly 2, and along the front and rear directions, the chip assembly 3/electrical contact portion 322 is closer to the locking assembly 4 than the ink outlet assembly 2, when the ink outlet assembly 2 is working The generated vibration is less likely to be transmitted to the chip assembly 3/electric contact portion 322 and the locking assembly 4. Even if there is vibration transmitted from the bottom to the top of the ink cartridge, the locking assembly 4 can effectively suppress the vibration, thereby ensuring the chip assembly 3/electrical contact Stable electrical connection between the part 322 and the device; along the front and back directions, the ink outlet assembly 2 and the chip assembly 3 are located in front of the locking assembly 4, and when the ink cartridge is installed, the chip assembly 3 and the locking assembly 4 will not be subject to external interference , especially for the chip assembly 3, in the first position, the chip assembly 3 is only exposed above the ink cartridge, and the user's hand will not touch the electrical contact portion 322, and in the second position, the chip assembly 3 Still covered by the locking assembly 4, the user's hands or external components will still not touch the electrical contact portion 322, and the working stability of the chip 32 is guaranteed.
